2.66 release: February 21th, 2013.
This release contains long awaited features like:
- Rigid body physics simulation
- Dynamic topology sculpting
- Matcap display.
Other new features include
- Cycles hair rendering
- Aupport for high pixel density displays
- Much better handling of premultiplied and straight alpha transparency
- A vertex bevel tool
- A mesh cache modifier
- A new SPH particle fluid
2.66a update: March 6th, 2013.
The Bevel tool supports bevelling individual vertices in addition to edges now, with one or more segments.
The image pipeline has be refactored to handle transparency in images better and compatible to standards. There are two alpha types for images that are useful for different purposes, and we now try to automatically do the right conversions and operations.
New Mesh Cache modifier can apply animation from external files onto a mesh, a new UV Warp modifier can rotate, scale and translate UV maps on a mesh using objects or bones, and the Laplacian smooth modifier now supports shape enhancement.
The character physics type received a number of new options, profiling and debug information has been cleaned up, and simple shadow maps can now take clipped alpha transparency into account.
A new SPH particle fluid solver was added, designed for more physically accurate results.
Collada import and export was improved for animation: shape keys are now supported, and the armature modifier has been made more stable, respecting axis orientation and scene scaling.
New features include vertex color baking, more efficient ambient occlusion baking for multires meshes, edge based UV stitching, more control over mapping texture brushes for texture painting, gradient tools for weight painting, and a translate node for the compositor.
